Write the balanced chemical equations for the following reactions and identify the type of reaction in case.
Ethene is burnt in the presence of oxygen to form carbon dioxide, water and releases heat and light.

Explanation

To write the balanced chemical equation for the combustion of ethene (C2H4) in the presence of oxygen (O2), we follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced equation for the combustion of ethene can be written as:
\[ \text{C}_2\text{H}_4 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \]
